Title: Electrophotographic photoreceptor
Inventor: KITAGAWA KYOKO
IPC: G03G5/14
Filed: 1997-06-06
Abstract: PROBLEM TO BE SOLVED: To provide a photoreceptor having an undercoat layer which has a low resistance even when the thickness is increased, and is highly resistant to environmental change, and minimized in characteristic change in long-term use by containing a resin component, metallocene compound, and an electron attractive compound in the undercoat layer. SOLUTION: For example, a negatively charged function separating type electrophotographic photoreceptor is formed of a conductive base 1, an undercoat layer 2, and a photosensitive layer 6 containing a charge generating layer 3 and a charge transport layer 4. The undercoat layer 2 contains a resin component, a metallocene compound, and an electron attractive compound. The metallocene compound used in the undercoat layer 2 is a compound formed of two or three cyclopentadienyl rings and various transition metals. The undercoat layer 2 using the electron attractive compound together with the metallocene compound has a low electric resistance, compared with an undercoat layer containing the metallocene compound alone.

Title: Printed board transfer device
Inventor: YONEKAWA SHOJI
IPC: H05K13/02
Filed: 1996-06-11
Abstract: PROBLEM TO BE SOLVED: To enable a printed board to be transferred and positioned keeping both its sides clean by a method wherein a pressing plate is so controlled detecting its load displacement so as to move towards a take-out end by the load displacement to impose a certain load on the surface of a printed board constantly. SOLUTION: A printed board is transferred to a die bonding device through a transfer path 101. A stocker 102 is possessed of a take-out end through which the printed board is taken out as it slides. A pressing plate 103 presses down the stacked printed boards with an adjustable load. The printed boards are taken out by a chuck 104 one by one. A separator 105 enables one out of the printed boards located at the take-out end to be taken out corresponding to a takeout action. A control 106 controls the pressing plate 103 so as to make it impose a certain load on the surface of the printed board detecting the load displacement of the pressing plate 103. With this setup, dust attached to the rear of the printed board is removed by cleaning in transit.

Title: Manufacture of semiconductor integrated circuit
Inventor: KAWAKAMI KENICHI
IPC: G03F9/00
Filed: 1998-05-29
Abstract: PROBLEM TO BE SOLVED: To make high-accuracy alignment possible even when a polishing process is performed by forming an alignment mark of a material having a sufficiently larger mass and density than a thin film formed on the mark has. SOLUTION: After a tungsten (W) layer 23 is formed on a wafer 11, a resist 25 is applied to the W layer 23 and exposed correspondingly to an alignment mark 24 for electron beam so that the resist 25 may be left at the part of the mark 24. Then the mark 24 is formed by removing the W layer 23 except the part coated with the resist 25 and a gate material layer 26 is deposited on the wafer 11. After the layer 26 is deposited, another resist is applied to the upper surface of the layer 26, and the center of the groove of the mark 24 is detected by detecting reflected electronic signals by scanning the mark 24 with an electron beam.  Since the mark 24 is formed of tungsten, the mass and density of the mark 24 are largely different from those of the gate material layer 26, and the reflected electronic signals when the electron beam is projected upon the part of the mark 24 are largely different from those when the electron beam is projected upon the other part. The center of the groove of the mark 24 can be detected accurately.

Filed: 1991-05-24
Abstract: PURPOSE:To prevent the wasteful consumption of a material and reduce the cost by a method wherein the first cutting cycle of a second circle and following cycles is started when a command cutting length is equal to the running distance of a material from a material position situated during the starting of a last cutting cycle. CONSTITUTION:When a preceding sequence is a running cutting and fixing cycle, a command SY is delivered to a gate G1 by means of a continuous running cutting and fixing cycle deciding part 24. An adder 13 adds a cutting length L2 and the number Lp of pulses, stored in a cutting length memory part 22, and a value PCOUNT of a pulse counter 12 of the last cycle of a preceding sequence stored in a cutting starting counter memory part 17. The pulse counter 12 reads a pulse PS of a pulse generator 5 and is delivered as FEEDC to a comparator 14. The comparator 14 opens a gate G1 when FEEDC is higher than or equal to PCOUNT + Lp, and the FEEDC is delivered to the cutting starting counter memory part 17 through a gate G4.

Title: Gasification of liquefied natural gas
Inventor: ASADA KAZUHIKO
IPC: F17C9/02
Filed: 1980-10-24
Abstract: PURPOSE:To effectively utilize excess energy contained in natural gas by installing a regenerator in the middle of the liquefied natural gas passage and by returning natural gas from an expansion turbine, through the regenerator, to the liquefied natural gas passage. CONSTITUTION:A regenerator 7 is installed in the middle of the liquefied natural gas passage 6a, 6b. The regenerator is connected to an expansion turbine 5 and also to the liquefied natural gas passage 6a through a pump 8. A part of the gasified natural gas flows into the expansion turbine 5 and drives the expansion turbine 5. At the same time, gas itself expands adiabatically, exchanges heat with the liquefied natural gas by means of the regenerator 7 and returns to the passage 6a. Thus, aside from gasifying the liquefied natural gas and supplying the gasified natural gas, excess energy of gas is effectively utilized.

Title: Controller for amount of ventilation
Inventor: KIKUCHI SHIRO
IPC: F04C29/04
Filed: 1990-06-11
Abstract: PURPOSE:To prevent a compressor from being cooled excessively and restrain generation of a drain and extend the life of lubricating oil and achieve energy saving and noise reduction by providing temperature sensors in a package and an oil separator portion, and stopping a ventilating fan or controlling the number of revolution of the fan below a specified temperature so as to control the amount of cooling wind. CONSTITUTION:A reference temperature is set in advance by a temperature sensor 11 for detecting the temperature of the discharge portion of a compressor 3 and ambient temperature or a relay, and when e.g. the temperature of the discharge opening is less than 70 to 75 deg.C and the ambient temperature is less than 40 to 45 deg.C a ventilating fan 10 is stopped or the number of revolution of the fan 10 is controlled. The amount of ventilation is thus controlled in order to prevent temperature lowering and realize efficient operation of the fan 10. In this case the ambient temperature of the compressor 3 takes precedence over the temperature of the discharge opening; when the ambient temperature is less than the reference temperature operation of the ventilating fan 10 is maintained even with the temperature of the discharge opening being less than the reference temperature and reliability of electric parts is thus maintained and the main body of the compressor 3 is prevented from being cooled excessively and generation of a drain is restrained and noise reduction is achieved.
